Before you start trying to removing the hubs and sensors . make sure the brake caliper pistons are free to move back and forward , In the shop I have found some to be frozen and others to be sticky and not releasing causing all kinds of brake faults.

Dosge has had issues in the past with wheel bearings. The problem sounds like a front speed sensor which if you have a 4wd come attached to new hubs. Sometimes rust and debris can become lodged between the hub and the sensor, if you are savvy you may be able to remove and reinstall the sensor without changing out these pricy hubs. I think that the truck may be getting the wrong signal from one of these sensors. Like I stated, the front two are located on the hubs and I believe on that year ram the sensor is located on the rear diff. People say these hubs are nearly impossible to get off. I have found that if you use a socket and extension, you can actually place the tool between the frame and the hub and use the power steering to literally pop the hub right off considering you were able to loosen the bolts. This is a project for somebody with some patience as rusty Rams can be a bear to fix. Please keep in mind that you may be able to change just the sensor. Of course, check the wiring and grounds to each unit as they can get caught up and you could just have a faulty ground. I know I am leading you in a few directions but I am sure that with patience and perserverence you can find and tackle this project. Good luck and let us know if you find your problem.

I had the same problem and it turned out to be one of the front speed sensors and the rear speed sensor as well. If you get a chance to look at all the speed sensors make sure the wires on the front aren't burnt from hot brakes. I have an 01 3500 4X4 and it was a pain to change the front sensor but the rear sensor took about 5-10 minutes, it's located in the middle of of the rear axle right on top. I bought both of mine on Ebay and cut the price in half.

check the sensors and connections may have loosened or knocked one loose if they look ok than have truck scanned most auto stores such as auto zone/advanced auto scan for free the trouble code will narrow the problem

The below test is generic, but gives you a general idea how to test the sensor. Most shops skip to the resistance test (at the bottom), if they do any test at all. A new sensor is $17 at autozone. Let me know if you have any questions.

A defective vehicle speed sensor may cause different problems depending on the computer output control functions. A defective vehicle speed sensor (VSS) may cause improper converter clutch lockup, improper cruise control operation, and inaccurate speedometer operation.

  • Prior to VSS diagnosis, the vehicle should be lifted on a hoist so the drive wheels are free to rotate.
  • Backprobe the vss output wire and connect the voltmeter leads from this wire to ground.
  • Select the 20-volt AC scale on the voltmeter.
  • Then start the engine.
  • Place the transaxle in drive and allow the drive wheels to rotate. If the VSS voltage signal is not 0.5 volt, or more, replace the sensor.
  • When the VSS provides the specified voltage signal, backprobe the VSS terminal at the PCM and repeat the voltage signal test with the drive wheels rotating.
  • If 0.5 volt is available at this terminal, the trouble may be in the PCM (powertrain control module).
  • When 0.5 volt is not available at this terminal, turn the ignition switch off and disconnect the wire from the VSS to the PCM.
  • Connect the ohmmeter leads across the wire. the meter should read zero ohm.
  • Repeat the test with the ohmmeter leads connected to the VSS ground terminal and the PCM ground terminal.
  • This wire should also have zero ohm resistance. If the resistance in these wires is more than specified, repair the wires.
  • The condition of a speed sensor can be checked by going through the diagnostic routines for the system.
  • If this test indicates that a sensor is faulty, the sensor should be replaced.
  • Speed sensors can also be checked with an ohmmeter. Most manufacturers list a resistance specification.
  • The resistance of the sensor is measured across the sensor's terminals.
  • The typical range for a good sensor is 800 to 1400 ohms of resistance

How do I adjust the timing on a 2001 Dodge Ram


There is no adjustment for the timing on a 2001 dodge ram 1500 4x4 5.2 liter . and the most likely cause on th eother problem is the abs speed sensor on the rear differential it is bolted to the top of the differential housing with a 10mm bolt remove it slowly in a twisting motion and put new differential grease on the o-ring slide it in and bolt it down and remeber to clear all codes or the sensor will run off of old paremeters

I Have a 2002 Dodge Ram 2500.Both the ABS and Brake Lights are on


Hi!!

Did you have the ABS sensors checked ?? The brake fluid level when low also activates the Brake and ABS lights?? Drive truck to an AutoZone store and ask to have computer codes scanned. This is a free service for all customers. This will help you to pinpoint the problem.

Good Luck!!

Probably either your PCM or Vechile Speed Sensor. The VSS sends an AC (alternating current or sine) wave to the PCM and according to the frequency of the wave, tells the PCM the speed with which the vehicle is moving. It will be mounted to your transaxle, and I would look into this before the PCM.

Random lights coming on in the dash and stalling occasionally


See if you can find out if there is a code for the check engine lite and the abs, those can be related if the speed sensor located on the top of the rear axle is intermittantly failing. That sensor sends the speed signal to the pcm and the abs controler witch will also turn off the cruise control.

Check engine light: Turn the key on three times in succession and wait for the codes. What are the codes?
Brake ABS light: When did you last have the brakes serviced?
No AC: Do you park your truck/car in a garage? Check the AC housing for leaves and debis which will burn out the AC fan motor.
